Hehe the trick is.......I duplicate the final image as many times as the number of filters I want to use! Examples:1) hard light : fill the layer with your choice of solid colour, text, gradients etc. This layer type adds like a colour film over your pic, harmonizing the colours 2) overlay: similar to hard light, but the effect is more transparent than hard light. ^^

3) gaussian blur + layer mode on overlay : a nice softening effect4) sharpness : coupled with gaussian blur on another layer, this allows you to have defined edges and keep the glow effect from the blur/overlay combo
